Shaking table test and analysis method on ultimate behavior of slender base-isolated structure supported by laminated rubber bearings.

The article presents a study which investigates the ultimate behavior of slender base-isolated buildings caused by buckling fracture in laminated rubber bearings through the use of shaking table tests in Japan. It mentions that the practical use of base isolation which is a structural technology is on the 1980s which was effectively recognize since the 1995 Hyogo-ken Nanbu Earthquake. It states that the shaking table test was performed with unidirectional input during the occurrence of fracture in the bearings. The result of the study shows that the buckling behavior of the bearings can be expressed in the large deformation range through the proposed model, time history response analysis.
